Abstract

Bei bekannten Druckregelventilen ist der Ventilsitzkörper mit der Membran verbunden und der Ventilschließkörper an einem an einem Grundkörper befestigten Pfosten gelagert, wodurch sich ein großer Herstellaufwand ergibt.In known pressure regulating valves, the valve seat body is connected to the membrane and the valve closing body mounted on a post attached to a base body, which results in a large manufacturing effort.

Bei dem neuen Druckregelventil ist der Ventilschließkörper (30) direkt am Grundkörper (24) des Druckregelventils vorgesehen, so daß beim Abheben des Ventilsitzkörpers (43) mit der Ventilsitzfläche (44) von dem Ventilschließkörper (30) abzuregelnder Brennstoff von der Druckregelseite (45) der Membran (40) über die Ventilsitzfläche (44) und einen Rückströmkanal (54) auf die Rückströmseite (47) der Membran (40) strömen kann.The valve closing body is in the new pressure control valve (30) directly on the base body (24) of the pressure control valve provided so that when the valve seat body (43) is lifted off with the valve seat surface (44) from the valve closing body (30) fuel to be regulated from the pressure control side (45) the membrane (40) over the valve seat surface (44) and one Backflow channel (54) on the backflow side (47) of the membrane (40) can flow.

Das Druckregelventil eignet sich besonders zur Verwendung bei Brennstoffversorgungsanlagen von Brennkraftmaschinen.
